They absolutely do sell to those organizations and governments. Otherwise they wouldn't bother maintaining a conforming, byzantine test suite. It's a checkbox that's useful for business purposes rather than technical ones, just like FIPS.
Correct. I used to work alongside folks who did research and operations at places like JPL and JHU’s APL. They very much cared about things like UNIX. (They also really enjoyed having computers that ran Mac, Windows, and Linux back when that was much more a given for someone to do.)
There’s this idea floating out there, and it’s been out there for a long time, that serious academic/research work isn’t to be found on the Mac, or that you can’t run whatever software you want (you absolutely can). These ideas do not track reality.
